Usage Information
LACP on the VLT ports (on a VLT switch or access device), which are members of the VLT, are not brought
up until the VLT domain is recognized on the access device.
During boot-up in a stacking conguration, the system must be able to reach the DHCP server with the
boot image and conguration image. To receive an oer on static LAGs between switches, only untagged
DHCP requests are sent to the DHCP server. Congure the DHCP server to start in BMP mode.
If the switches are connected using LACP port-channels (for example, the VLT peer and top of rack [ToR]),
use the port-channel option on the ToR-side conguration to allow member ports of an ungrouped
LACP port-channel to inherit VLAN membership of that port channel. This ensures untagged VLT peer
device packets reach the DHCP server on the ToR.
To ungroup the VLT and port-channel congurations, use the no lacp ungroup member
independent command on a VLT port channel.
